The Bush administration has begun prepping senior lawmakers for approval of a draft agreement on keeping US troops in Iraq. On Thursday, Defense Secretary Robert M. Gates and Secretary of State Condoleezza Rice briefed senior lawmakers on the details. The proposed draft agreement calls for US troops to leave Iraqi cities by next June and completely withdraw from Iraq by 2012. US soldiers would retain immunity from prosecution for all actions committed in combat. The US would retain all jurisdictions over its troops’ actions unless for actions committed “off-duty” and away from US bases. Critics have dismissed the provision because US troops seldom leave their bases in Iraq unless on authorized missions.
